Figure 1-2: Display

KT 74 Pilot's Guide



The display shows the following indications:

• Active Mode: the Active Mode indicator shows the mode that is currently set on the Mode Knob. See section 1.4.

• Pressure Altitude: The reported pressure altitude is displayed as a Flight Level (FL), which is the pressure altitude in hundreds of feet. When non-standard atmospheric conditions apply, this may not match the altimeter indicated altitude, but will be correctly displayed by the Air Traffic Control (ATC) radar.

• Squawk Code: The current squawk code selected by the Numeric Buttons. See Squawk Code Entry in section 1.5

• Flight ID: The aircraft call sign entered on your flight plan. See Flight ID Entry in section 1.6

• IDENT Indicator: The IDENT Indicator shows when IDENT mode is active. See section 1.5.

• Reply Indicator: The Reply Indicator is active when the transponder replies to interrogations.

• Deviation Pointer: When altitude monitoring is in use, a small deviation pointer appears adjacent to the altitude display on the transponder. See Altitude Monitor in section 1.6.

• Warning message: See section 1.7 • Fault Annunciation: See section 1.8.

Light Sensor If connected to a lighting bus, the KT 74 will adjust the brightness of the front panel lighting based upon the lighting bus input. If no lighting bus input is detected, the KT 74 will automatically control the front panel lighting based on the ambient light sensor. The dim point for the Liquid Crystal Display (LCD) backlight illumination can be adjusted by using the configuration mode as described in section 1.9 of this guide.

1.4 MODE KNOB

Figure 1-3: Mode Knob

The mode knob to the right of the display controls the power to the transponder and the operating mode. The mode knob has the selections that follow:

OFF Power is removed from the transponder.

SBY The transponder is on, but will not reply to any interrogations.

ON The transponder will respond to all interrogations, but altitude reporting is suppressed.

ALT The transponder will respond to all interrogations. When airborne, the transponder should always be set to ALT unless otherwise directed by Air Traffic Control. Aircraft installations that include a gear squat switch or other method of air/ground determination will automatically select surface reporting mode on landing or when taxiing. The mode indicator will read GND.

1.5 PUSH BUTTONS

Figure 1-4: Push Buttons

IDENT Press the IDENT button when ATC instructs you to “Ident” or “Squawk Ident”. This activates the SPI pulse in the transponder replies for 18 seconds. IDENT will appear in the display.

VFR Pressing the VFR button sets the transponder to the pre-programmed VFR code. Pressing the button again restores the previous squawk code. Pressing the VFR button while in Flight ID editing mode changes the Flight ID to the pre-programmed ID set up during configuration of the transponder.

FUNC Pressing the FUNC button provides access to the flight timer, stopwatch, Flight ID entry, ADS-B monitor (depending on installation) and altitude monitor function. See section 1.6 below.

ENT The ENT button confirms selection or presented options. 0-7 The numeric buttons are used to change the squawk

code and as part of the data entry selections.

KT 74 Pilot's Guide



Squawk Code Entry Press any of the numeric buttons (0 through 7) to change the squawk code. A new squawk code is set when the fourth digit is entered. If the code entry is not completed within 7 seconds, the changes are ignored and the previous code restored.

Some standard squawk codes are listed below:

• 1200 VFR code in the USA

• 7000 VFR code commonly used in Europe

• 7500 Hijack code

• 7600 Loss of communications

• 7700 Emergency code

1.6 FUNCTIONS

Figure 1-5: Functions

The different KT 74 functions are accessed using the FUNC button.

The functions displayed vary depending on whether the aircraft is airborne or is on the ground (squat switch or other method of air/ground determination installed) and has the GPS input enabled or not as shown in the following tables.

Each function is described in more detail below:

Flight Timer Press the FUNC button once to display the Flight Timer. The Flight Timer records the time for which the transponder has been powered on and operating in flight mode – either ON or ALT.

KT 74 Pilot's Guide



Stopwatch Press the FUNC button twice to display the stopwatch. The stopwatch can be used as a convenient timer. Pressing ENT will reset and start the timer. Pressing ENT again will stop the timer.

Flight ID Entry Press the FUNC button three times to display the Flight ID entry screen. The edit the Flight ID using the numeric buttons. The lower portion of the display shows the alpha numeric characters selected through multiple presses of the numeric buttons. When the correct character is shown in the flight ID section of the screen, press the ENT button to accept and advance to the next digit. The flight ID is terminated with a “space” character located on the 7 button. When ENT is pressed on the end space, the new Flight ID will replace the previous value. If a button is not pressed for 7 seconds, the changes are ignored and the previous code restored.

The Flight ID should correspond to the aircraft call sign entered on your flight plan. If no flight plan is active, the aircraft registration should be used as your Flight ID. Use only letters and digits. If the Flight ID is less than 8 characters long, enter the “space” character (7 button) to end it.

Altitude Monitor Press the FUNC button four times to display the Altitude Monitor enable screen. The Altitude Monitor activates an audio annunciator or annunciator light (depending on installation) when the aircraft pressure altitude differs from the selected altitude by more than 200 feet. Pressing ENT toggles the altitude monitor at the current altitude.

When altitude monitoring is in use, a small deviation pointer appears adjacent to the altitude display on the transponder.

KT 74 Pilot's Guide



ADS-B Monitor Press the FUNC button five times to display the Altitude Monitor screen The ADS-B Monitor is only available on installations that include an ADS-B position source. The ADS-B Monitor provides a display of the position information that is being transmitted in ADS-B position reports. This can provide confirmation that the correct information is being transmitted, particularly where the Global Positioning System (GPS) source is remote from the transponder.

In the event that valid position information is NOT available from the GPS, the latitude and longitude display will be replaced by dashes. If no valid latitude and longitude is shown, then ADS-B position information is NOT being transmitted.

Loss of ADS-B position information will also result in a WARNING message being displayed.

1.7 WARNING MESSAGES If the transponder detects a problem, the screen will indicate WARNING and a brief statement of the problem. Depending on the nature of the problem, your transponder may not be replying to interrogations. Note the message on the screen and pass that information to your avionics maintenance organization. The WARNING message should clear when the event has cleared. Press ENT to clear the message at any time; if the fault is still present the message may reappear.

1.8 FAULT ANNUNCIATION If the transponder detects an internal failure, the screen will indicate FAULT and a brief statement of the problem. No replies will be made to interrogations when a fault is detected.

Some FAULT indications can be recovered by switching the transponder off and back on again, although in all cases a FAULT code implies that there is a fault with the transponder or the installation. Note the FAULT message at the bottom of the screen and pass that information to your avionics maintenance organization.

KT 74 Pilot's Guide



1.9 CONFIGURATION MODE The system is configured when it is first installed by your avionics installer. Configuration items include the Mode S aircraft address, the interface to the other aircraft systems, the aircraft category, and the pre-programmed values for VFR squawk code. To view or change these settings you must use Configuration Mode.

Do not use Configuration Mode in flight. Check with your avionics installer before changing the configuration.

To enter configuration mode, hold down the FUNC button while switching on the transponder. Configuration items can be changed using the numeric buttons (6 for down, 7 for up) and the ENT button to accept the selection. Pressing the 2 button will move back to the last menu item. Pressing FUNC advances to the next configuration item. When configuration is complete; switch the transponder off. When it is switched back on the transponder will use the new configuration.

1.10 LOW TEMPERATURE OPERATION The KT 74 is certified to operate down to -25°C; however under cold operating conditions, the display update rate may be slowed but functional. The KT 74 incorporates an integral heating element in the front panel to automatically raise the temperature around the display. During cold operating conditions, a warm up period of 5 minutes minimum is suggested.
